[Dovecot] v2.2 getting NULL pointer reference with shared namespace in mailbox_tree?
I stumbled over another segmentation fault:

I'm not familiar with gdb / debugging. gdb bt full is following but I'm afraid line numbers are not yet correct, are they? Compiler is gcc 4.5.2 output of make command while building dovecot does not show "-O"... (also tried "-O0" before ... as mentioned on some web pages)

Yeah, for some reason they're wrong.
I can't seem to be able to reproduce this. What's in the user's subscriptions file?
Did some doveadm mailbox (un)subscribe -u ...
If the file subscriptions in the mailbox of this user is
a) empty => crash
b) user.otherexistinguser.existingfolder => crash
c) user.other... INBOX => okay
d) INBOX => okay
d) test => okay
It seems that with an active shared namespace one needs to have at least one folder in the private namespace in this file.
With no shared namespace the list may be empty.
(the client did not automatically subscribe to mailboxes (before the lsub))

Oh, figured out the crash: http://hg.dovecot.org/dovecot-2.2/rev/6f5b14d4ad56
You most likely want to have subscriptions=no for your shared namespace. Also you most likely want to enable ACL plugin.
b) user.otherexistinguser.existingfolder => crash
Note that this should be user/otherexistinguser/existingfolder
You most likely want to have subscriptions=no for your shared namespace. Also you most likely want to enable ACL plugin.
Yes - thank you for your comment! The ACLs I had configured before are not enabled in this minimalistic configuration because of crashes when running doveadm backup -R ... imapc: with ACLs enabled.
You wrote that you are continuing debugging "my problem". Regardless of this, should I investigate / file this ACL (related) bug?
